如何使用蓝牙在应用程序内发送.apk文件 [英] How to send .apk file inside app using Bluetooth

问题描述

有没有办法在应用程序中使用蓝牙发送 .apk 文件？
（例如我们启动app然后使用应用程序内的分享图标发送 .apk 文件）

Is there any way to send .apk file using Bluetooth inside the application? (for example we launch app and then send .apk file using share icon inside app)

推荐答案

假设您想发送自己的应用 .apk ，这很简单：

Assuming you want to send your own app's .apk, it's quite simple:

// Get current ApplicationInfo to find .apk path
ApplicationInfo app = getApplicationContext().getApplicationInfo();
String filePath = app.sourceDir;

Intent intent = new Intent(Intent.ACTION_SEND);

// MIME of .apk is "application/vnd.android.package-archive".
// but Bluetooth does not accept this. Let's use "*/*" instead.
intent.setType("*/*");

// Only use Bluetooth to send .apk
intent.setPackage("com.android.bluetooth");

// Append file and send Intent
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(filePath)));
startActivity(Intent.createChooser(intent, "Share app"));
